Abstract：The influence of pulse magnetic field on the solidified structure of steel was explored by use of high temperature laser confocal microscope equipped with independently developed pulse magnetic field generator. In the melt solidification phase of applying different voltage, analysis of different voltage of pulse magnetic field impact on final solidification organization. The results showed that the microstructure of the sample with the magnetic field is obviously refined compared with the sample without magnetic field. And with the increase of excitation voltage, the solidification structure is obviously refined. The pulse magnetic field voltage is increased from 10 V to 50 V, the average grain size of the sample is from 720 μm to 416 μm.
